The present invention relates to a process for cleaning the waste usedin railroad car Lournal .boxes and machinery therefor and as for itsprime object to provide an econom- 5 ical process which will eflicientlyclean the waste without destroying the fibers thereof and machinery foraccomplishing the steps of the process.

Generally the invention consists in pressall the oil and some of thedirt and grit from the old waste and delivering the same practicall dryto a combing machine. This com ing machine eliminates lumps in the wasteand draws the same into threads 15 and causes the formation of arelatively thin This comparatively thm layer of waste.

' layer of waste is delivered to another machine having a conveyor andmeans for rubbing the waste back and forth on the con- 20 veyor andsimultaneously delivering a stream of clean hot oil over the waste. hisclean hot oil assisted by the rubbing works all fine substance loosefromthe waste. The hot oil draining from the waste is filtered through agauze screen to be heated and used over again. The waste is delivered towhat is known as a sorting table which allows the surplus oil to drainoff after which the waste ,may be packea 1nto drums ready for use again.

With' the above and numerous other 9bjects in view as will appear as thedescription prceeds,the invention resides in certain novel steps in therecess and certain novel details of constructlon, and in the combinationand arrangement'of parts in the machinery as will be hereinafter morefully described and claimed.

therethrough taken substantially on the line 7-7 of Figure 5.

Referring first to the apparatus as shown in Figures 1 and 2 forsqueezing the oldoil from the waste, it will be seen that the numeraldenotes, a tank supported between corner legs 10. These legs 10 supportside rails 11 and end rails 12. Bearin' blocks 7 are slidablymounted onside rai s 11 as is indicated at 14 and have ends of rollers 2 and endsof rollers 15 journalled therein. Rollers 2 are smaller in diameter thanrollers 15. Springs 16 are interposed between the bearing blocks 7 forurgm the rollers 2 of each palr toward each 0t er. Shields 17 aremounted on side rails 11 by means of straps 18 and cover rollers 15 andterminate adjacent rollers 2. Hopper 1 is mounted on shields 17 so thatthe cotton may be placed in the hopper 1 by hand and when the rollersare in operation will pass between the rollers 2 and e ressed thereby.Blades 20 are journalled etween side rails 11 and through cranks 21 andspring 22 are yieldably held in engagement with rollers 2 to scrape anywaste therefrom which may have a tendency to stick thereto. The wasteand the oil, therefore, will fall into the tank 5. A conveyor frame 23is disposed on an incline and leads through one end of the tank to theinterior thereof and has an endless screen member 24 trained overrollers 25 journalled at the ends of the frame 23 and operable in anysuitable manner so that the waste will fall on the upper run of theconveyor structure which is moving upwardly and be led from the tankwhile the oil flows and collects in be drained ofi at 26 and anyconventional or preferred ears 26 are mounted on t e rollers 2 and meshwith each other. A beveled gear 3 is fixed on one of the gears 26 ofeach air and meshes with a beveled gear 4 carried y a filtered b driveshaft 27 operated by a motor 28 or in figures is made upof a pair oflegs 29 at each adjacent one end for.

end and a similar pair supporting a pair of lower side rails and a pairof upper side rails 31. A platform 33 is supported .on the intermediatelegs and one pair of end legs as at 34 and has teeth 35 rising therefromand arranged in series, each series of teeth being disposed below a rod36. These rods 36 are supported on cross members 37 and 38, the formerof which is disposed between the intermediate legs and the latter ofwhich is disposed below downwardly inclined extensions 39 of rails 31.Side rails 40 are disposed between the pair of intermediate legs and oneend air of legs 29 a slight difference above and 1n parallel ism withthe plate 33 so as to form slots 41. The numeral 42 denotes a platehaving a plurality of teeth 43 depending therefrom and extending inbetween the rods 36. An axle 44 is fixed to the plate 42 andextendsthereacross and beyond the side edges thereof. Bars 46 areslidable on the sides of the plate 33 and have humps 47 mounted thereonfor engaging rollers 48 journalled at the sides of plate 42. Pintles 49project laterally from the bars 46 through slots 41 and are engaged withpitmen 50. Pitmen 51 engage the ex tremities of axle 42. An operatorgear 53' is actuated in any suitable manner and 55 meshes with a gear 56meshes with gear 54 having co-axially fixed thereto a gear 55. Thepitman is eccentrically mounted on the gear 55. The gear with which thepitman 51 is eccentrically connected. The gears 55 and 56 are so meshedthat the movable portion of the comb including plate 42 and its teeth 43will be lifted on its rearward movement toward the gear 56 as the bars46 will be moved forwardly so that the hum s 47 will engage the rollers48 to effect this li ing and then the parts will be moved rearwardlytogether and the plate 42 will be moved forwardly before the bars 46 sothat the rollers will roll off the hump and the movable comb will movethe waste forwardly on the stationary comb formed by the plate 32 andthe teeth 35, thus threading the waste to remove all humps and formingthe same into a thin la er.

eferring now to Figures 5, 6, and 7, it will be seen that the numeral 60denotes a tank havin frames 61 and 62 of an inverted U- s'ha e structureas is clearly shown in Figure to straddle the same. Hexagonal rollers 62and 63 are rotatably mounted in the top of the tank and have trainedthereover an endless perforated conveyor 64 having seotional sideflanges 65 extending outwardly therefrom. The waste is delivered fromthe rake mechanism shown in Figures 3 and 4 to the left hand end of theendless conveyor as shown in Figure 5. A corrugated rubhing pan 66 ismounted on rods 67 and 68 carrie y bell cranks 69 and 70 respectively.These bell cranks 69 and 70 are pivotally mounted on frames 61 and 62respectively and are connected by connecting rods 71. The rubbing pan 66extends between the tops of the inverted U-shaped frames 61 and 62. Ashaft 73 is journalled in the upper portion of the frame 62 and isdriven by a pulley wheel 74 and has a chain and sprocket connection 75with a pump 76 and another chain and sprocket connection 77 with a shaft78 on one side of the tank 60 for driving a disc 79 having an off centerabutment 80. A ratchet wheel 81 is operatively connected with the drum63 and with a crank 82 and is engageable by the abutment 80. A pawl 83is mounted on the crank 82 for engaging the ratchet wheel 81. A link 84connects the crank 82 with the adjacent cantilever 70. An eccentric 86is operatively connected with shaft 73 for operating a pitman 87connected as at 88 with pan 66. The pan 66 is perforated and a pipe 89rises from the pump 76 and extends longitudinally over the pan 66 and isapertured as at 90 for the purpose of spraying hot oil on the pan, saidoil being heated by thermostatically controlled coils 91 in the bottomof the tank 60. Upon operation of the pulley 74 the shaft 7 3 causes therubbin pan 66 to move back and forth and the bell cranks raise the panon its backward movement and the conveyor operates with an intermittentmotion so that the waste delivered thereto is thoroughly rubbed and issaturated by the oil sprayed onto' the pan 66 which drips through theapertures thereof and saturates the waste and also cleans the waste ofany foreign matter therein. The crank 82 is returned by spring 95 and islimited in its return movement by an adjustable stop 96. A deflectorstructure 97 is mounted between the upper and lower runs of endlessconveyor and has sections inclining to the side and downwardly so thatthe oil from the perforated endless conveyor 64 will drip thereon andflow to the side of the tank and then down onto the deflectors 98 whichincline downwardly and inwardly so that all of the oil is delivered to agauze sheet 99 disposed over a supporting structure 100 above the oil inthe bottom of the tank and thus the oil is cleaned by the gauze sheet99. This gauze sheet is referably about twice as lon as the tank and iswound on a roller 101 and windable on a roller 102 so that when one halfthereof has become dirty the other half may be brought over thesupporting structure and the previous half cleaned.

It is thought that the construction, operation, utility, and advantagesof this invention will now be quite apparent to those skilled in thisart without a more detailed description thereof. The present embodimentof the invention has been disclosed in detail merely by way of examplesince in actual practice it attains the features of advanta e enumeratedas desirable in the statement a? the invention and the abovedescription. It will be apparent that changes in the details ofconstruction, and in the combination and arrangement of parts and in thesteps of the process may be resorted to without departmg from the spiritor scope of the invention as hereinafter claimed or sacrificing any ofits advanta es.

Having t as described our invention, what we claim as new is 1. Aprocess for cleaning waste comprising, first pressing oil from the wasteafter use, secondly raking the waste, and thirdly, simultaneousiyrubbing the waste under pressure and saturating and cleaning the samewith hot oil.

2. A process for cleaning waste comprising simultaneously rubbing thewaste under pressure and saturating and cleaning the same with hot oil.

- oil from the waste after it has been us 3. In a recess for cleaningwaste, the step of subjecting the waste to pressure between tworelatively movable members, moving such members to subject the waste toa rub bin action, and simultaneously with such I rub ing applying hotoil to the waste.

- 4. A process for cleanin journal box waste subsequent to use,comprising pressin old and subsequently raking the waste and saturatingand cleanin it with hot oil.

5. A process or cleaning journal box waste subsequent to use, comprlsingpressin old oil from the waste after it has-been use and subsequentlyrubbing the waste and simultaneously saturating and cleaning it withoil.
